MacBook overheating when BigSur installed
So, for whatever reason, my MacBook Pro has been overheating on Big Sur randomly, since when I updated it from MacOS Catalina. I updated it on Thursday, March 25th 2021.
MacBook Pro 13″, macOS 11.2

Give this a try:
How to reset the SMC of your Mac - Apple Support
Reset NVRAM or PRAM on your Mac - Apple Support - 2 to 3 times in succession
Boot into Safe Mode according to Start up your Mac in safe mode - Apple Support and reboot normally then check to see if the problem persists.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following;
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files
